It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2018-8833 and fix it if it is affected.\n\nWhat it is: CVE-2018-8833 is a high-severity memory corruption vulnerability in ICS-CERT Advantech WebAccess HMI Designer, published on 25 Apr 2018. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-8833 in the wild and no public exploit code.\n\nAffected product: ICS-CERT Advantech WebAccess HMI Designer. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2018-8833/ (Markdown: https://insights.sbomify.com/CVE-2018-8833/index.md)","id":"CVE-2018-8833","markdown":"https://insights.sbomify.com/CVE-2018-8833/index.md","name":"CVE-2018-8833","record":{"aliases":["GHSA-qv8h-5j9g-63mm"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"HMI design software","requires_auth":"none","summary":"Heap-based buffer overflow in Advantech WebAccess HMI Designer allows remote code execution via crafted .pm3 files.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"webaccess_hmi_designer","vendor":"advantech"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"Heap-based buffer overflow vulnerabilities in Advantech WebAccess HMI Designer 2.1.7.32 and prior caused by processing specially crafted .pm3 files may allow remote code execution.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Memory corruption in Advantech WebAccess HMI Designer","id":"CVE-2018-8833","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in Omron CX-One","id":"CVE-2018-8834"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-8832"},"products":["Advantech WebAccess HMI Designer"],"published":"2018-04-25","related":[{"cvss_score":8.8,"headline":"Memory corruption in Advantech WebAccess HMI Designer","id":"CVE-2019-10961","kev_date_added":null,"published":"2019-08-02"},{"cvss_score":7.8,"headline":"AzeoTech DAQFactory","id":"CVE-2021-42706","kev_date_added":null,"published":"2021-11-15"},{"cvss_score":7.8,"headline":"Use after free in Advantech WebAccess HMI Designer","id":"CVE-2018-8835","kev_date_added":null,"published":"2018-04-25"},{"cvss_score":7.8,"headline":"Memory corruption in Advantech WebAccess HMI Designer","id":"CVE-2018-8837","kev_date_added":null,"published":"2018-04-25"},{"cvss_score":5.4,"headline":"AzeoTech DAQFactory","id":"CVE-2021-42703","kev_date_added":null,"published":"2021-11-15"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["ICS-CERT"]},"summary":"Heap-based buffer overflow in Advantech WebAccess HMI Designer allows remote code execution via crafted .pm3 files.","url":"https://insights.sbomify.com/CVE-2018-8833/"}
